With three members who have logged more than 35 years with the band, including singer Kevin Cronin, REO Speedwagon is one classic rock road act that deserves its fans' ongoing love and respect — whether they jumped on the bandwagon with FM faves such as “Riding the Storm Out” or '80s smashes like “Keep on Loving You.” The band plays the San Antonio Rodeo on Friday night at the AT&T Center.
